Claims. 1 i r.

This invention relates to wringers constructed and designed for use in connection with any type of domestic `washing machine or automatic laundry unit requiring wringers.

One of the main objects of the present inven` tion is to provide a wringer of compact construction. with a substantial; minimum overall vertical height and which includes all of `thesafety features for safe operation and one that fulfills and eicently carries out all of the functions re-. quired by a standard wringer machine. 1

Another object of the present invention is to provide a wringer of the type described which embodies a safety `release mechanism eiiiciently adapted and constructed for use in thissmall vertical height wringer.

The design of `the present Wringer embodies a construction wherein the` usual upper .or top .frame has been eliminated and the structure incorporates as another object of the inventionthe novel arrangement of using the shaft of v.the upperroll to function as the upper frame so that this upper rollstructure and its associated parts provide a means to absorb the reactionary force between the rolls created by the pressuremeans and by the clothes as the latterare passed be- A further feature of the present wringer is the introduction of a release bar so shaped andarranged to comprise a wringer top and to coact r with the main wringer frame to complete the wringer housing. Such a wringer top comprises a release bar connected with the safety release mechanism for the'purpose of operating thelatter. Since this `release bar `forms the wringer top and extends `substantially the `full length of the wringer, it is disposed in the best possible position to be operated by a reflex action ofthe user in the event that the latter should accidentally get his or her hand caught in the wringer rolls. The natural tendency would beto thrust forth the free hand against the wringer` which would be the wringeritop and this particular action supplies morethan enough force necessary .l for releasing the latch mechanism which permits separation of the wringer rolls at theiinstant that therelease bar is touched.v .r i l In connection with the object immediately above, it is another feature of the present `wringer to includea drivemechanism which has sepa;- rable members that drive the wringer rolls and which members are parted at the instant that the safety release mechanism is operated by con- Y tact with the release bar top of thewringer so that the:driveissimultaneously interrupted with ier the parting of the wringer rolls under the action described... i n I.

.There are other features and advantages asso# H- piated with `the wringer of the present constructien such as providing a latch mechanism which islfconstructed to .include means for limiting the exploding act of the wringer as occurs through the operation ofthe wringer top release bar. Other advantages and features not already referred to will appear in the following description of the wringer construction having reference to the accompanying drawings illustrating a preferred embodiment thereof.

During the release-action of the wringer it should be noted in-Fig. 'Z-thatthe ultimate vertical swinging movement; of the upper frame and the upper roll is limited bymeans of wringer `beyond va predetermined -maximum AIn all cases,Y however, whenever the-reset lever is; operated to again relatch the mechanism for holding the upper and lower framesv in operative relationto cause contact between the-wringer rolls, the top 3, comprising the release bar will resume its normal centralized positionwith respect to the base frame by means illustratedin` VAFigs. 8 and 9. and through the inherent resiliency of this top member, such action being. controlled Ybylthe connection ,of the top lmember against the flat rend of the shaft 21 through thefasteningscrew |00. Furthermore, it should be noted that the .release bar comprising the wringer top 3 is of very light construction and merely com- -prises a housing unit-for covering the upper-portion of the wringer and to yfvanclosethe roll chamber which is provided by the lower open base frame construction. This centralizing Aor-positioning of the top in proper alignment withthe wringer base structure is alsoaidedthrough the spring 89 which lifts the latch bar vertically causing the pin 94 of the `actuator to dropinto central relationship with'respect to the-camslot l96 in the release barvl. Thus .the spring action described causes theactuator 9| toresume its verticalposition with the ears 92 and 93 centralizingthe wringer top 3 into the position shown in Fig. 5 with respect to the lbalance Of the `comprising the wringer top 3 may be .shifted Therefore, the release bar f becauseof the small overall vertical dimension of -th is-.Wr,inger.

by the breadth and scope of theappendedclaims submitted herewith.

What I claim is:

41..` A' roll wringer comprising a Vmain frame, 4upper and lower rolls, meansV for guiding the lower -rollrelative to said main frame, a non-rotatable .shaft'for said upper roll and having oneend f pivotallyconnected withsaid main frame and vhaving the yother end free, releasable latch means 4tohold the free-end of said shaft and the supported upper roll in predetermined relation-.with

respect to the lower roll, pressure means carried by said main frame and acting upon one of said Y rolls to hold both rolls in active roperative contact with each other, said rolls being separable, upon release of said latch means, through the pivoting l of said upper roll shaft,and drive means for said Arolls including cooperative drive members, one of `said members being carriedupon said` shaft; and

,sideways in one direction or thev other Aand lateral- -ly with respect to the length of the wringer in one direction or the other to cause arelease of the safety mechanism, and such release bar 3 moves directly upwardly with the vertically swingable upper frame comprisingthe shaft 2'|, this -which is mounted upon the lower frame by means of the ears 29 that comprise Aan integral part of the gear casing I. Ajvery compact wringerstructure is hereby produced having a small overall vertical height minimizing the effort whichA` must beexpended by the housewife in reaching over the top of the wringer while feeding clothes theretovor guiding the same away therefrom. Also if a wringer of this type is installed in a standard washing machine wherein'a wringer column employed for using the tube itself of the washer forhousing the wringer, sucha wringer vwould be well adapted as a disappearing wringer in view of the fact that the necessary vertical motion yfor nesting the `wringer w is considerably reduced;
